Re: Help about Message Box

Hi DM,
Thanks and congrats on starting a thread like this. I have gone through almost all the posts in thread.
I have one query about my trading system. I want a message box to be flashed and a beep when buy or sell condition is satisfied. Say for example if Reliance becomes buy then it should flash message like this Reliance is buy. It should also flash the time at which this signal was generated.

Thanks in advance.

Cheers :!!!!!

Hi,

You can use PopupWindow() method - as explained here : http://tradinganalysis.co.in/AmiBroker_Help/index.html?popupwindow.html

Hope this helps.

Hi DM, I'm new to the group and to ALF, and am so glad to have found this thread. I've just finished reading through the thread than have learned much more than I culled from several hours wrestling with AMIBroker's documentation. Thank you very much for your efforts. --Kirk

great topic. thanks for the effort.

one topic if i could suggest:
when you move the mouse around, there is a pop up window to show price info, how do you add information there for display?


another issue i am having is to find pivot bar that's is the low/high in +/- n days (n is param). not if there is easy clean way with array solution.

thanks again

Hi All,
Can somebody convert this into an amibroker afl..
Scan for stocks closing above 21 Week EMA with volume 4 times the weekly volume.
Also plot the 21 week EMA on Daily chart.

Hello Friends,
I started this thread because I did lot of googling but I have not yet found any good site that helps "How to write AFL". I know there is a site contains AFL Library but it is not sufficient. I have a computer background, so I understand how the process goes, I can write very basic AFL also. But I want active participation of seniors, those have very good knowledge of writing AFL. I know many members are here with good knowledge of AFL. Please help new users as well as intermediate user.

Happy Trading

Dear Mr.Debarghya Mukherjee,

Kindly help me in making an AFL as below:

Condition A (Eg: Ema crossover)
PREVIOUS DAY: Stocks meet Condition A in EOD charts.

Condition B (Eg: Break of Hi / Lo of previous day)
TODAY: Such short listed stocks to be scanned in Intraday Charts for break of previous day Hi / Lo (Condition B)

Is it possible to combine condition A & B in one AFL, so that the scanning is done TODAY in Intraday charts ?

Separate AFLs for Condition A & B can be made, but how to combine into one AFL as first condition is EOD & second is Intraday real time !

Thanks,
